Description
The ebmpapst R3G250-PR17-W9/G01 is a high-power 3-Phase EC Centrifugal Fan with an impeller size of 250 mm and dimensions of 250 x 123 mm. This backward-curved fan is part of the high-efficiency RadiCal series, driven by a powerful GreenTech EC external rotor motor. Operating on a 3-phase 380-480 VAC supply, it features a robust input power of 1160 W and an output power of 998 W. At its peak speed of 4000 RPM, it delivers a massive airflow of 1500.8 CFM (2550 m³/h). This model is specifically engineered for high-pressure industrial applications such as EC energy-saving retrofits in Fan Filter Units (FFU) and precision cooling systems. With integrated speed control, IP55 protection, and a glass-fiber reinforced composite impeller, it provides superior aerodynamic performance and long-term reliability in demanding cleanroom and industrial environments.
